WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?


#1. YOU DON'T NEED TO USE BOTH WIFI AND PoE


Yes, you can't use both Wi-fi and PoE at same time. While you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.


Before you decide to buy an IP camera or a whole IP camera system, you should analysis the set up environment and research which functions you want to accomplish.


WiFi or PoE, which is the better? As a senior technician who may have four years in training video surveillance industry, my response to this question is PoE is the recommended choice.



#2. WHAT'S WIFI


WiFi is some sort of wireless technology that allows network devices transmit data through cordless indication (2.4GHz UHF music group, 5GHz SHF strap).


Obviously, after the IP camera facilitates WiFi, the camera can hook up your router without needing hardwired connection. WiFi can allow IP camera become portable, this is the advantage of Wireless.


But there are two downsides on WiFi, which can be; every gadgets require power, which means your IP camera still requires cable for connection.


So far, I haven't found any IP surveillance cameras are able to operate with electric batteries.



#3. HOW FAR Does indeed WI-FI REACH?


Limited WiFi transmission distance is another problem.


How far will Wi-Fi reach? It's not easy to answer this question.


When talking about WiFi coverage, we've a lot of things to consider including power rate of Wi-fi device, environment (interior or outdoor) and even more.


Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters indoor.


When Wi-fi devices will work outdoor without barrier, the transmission distance will be much significantly.


To increase the Wi-fi coverage or distance, you can install WiFi gain access to point. This access point (or hotspot) has a variety of about 20 meters (66 feet) indoors and a greater range outdoors.



#4. WHAT'S POE?


PoE means Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable (Kitty5/6) is the primary feature of PoE technology.


As long as your IP camera supports PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play installation, which greatly reduced the set up procedures, and get rid of the necessity of electricity cable and offer.


Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum power rate is to 15.4 W of DC ability (minimum 44V DC and 350mA) to each device.


In order to provide power for high electric power consumption devices, the IEEE connection made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.


PoE technology has been trusted in:

-           IP surveillance system ( Camera + NVR)

-           VoIP Phones

-           WiFi Access Point

-           Network Routers

-           Industrial devices

#5. Disadvantages AND Positives OF POE TECHNOLOGY


Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra ability cable or power supply.


The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable connection, there is no signal disturbance, no indication jamming.


For properly working of PoE devices, Power sourcing equipment (PSE) is vital component, it can be a network PoE switch, or an intermediary device such as PoE injector.


A PoE switch is much expensive when compared to a traditional network swap, which increased a little on cost.



#6. WIFI VS POE


No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for WiFi IP camera.

Ensuring the WiFi IP camera is installed within coverage of your Wireless router.


For more than one IP camera, PoE is preferred. PoE is much reliable than Wireless in terms of data transmitting.


Furthermore, an IP camera system based on PoE is much easier to manage, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).


From my personal investigation of surveillance market, I came across that Wireless IP camcorders are widely used for non-professional inside security, and PoE IP cameras are installed for outdoor surveillance system. But if you choose Wi-fi IP Camera please read article below.




So how would you determine which wireless IP camera suits your preferences?


Firstly, establish what you need. Many buyers often don't really know which kind of wireless IP camera suites and would gratify their needs. As a result, they get sucked into buying cellular IP surveillance cameras that are beyond what they want.


Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or excellent); what accuracy of data do you want to take? (HD images with or without sound) & most importantly, what's your budget?


 

Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.


Naturally, this feature will rely upon the environment where you would like to use the camera.


A broad skillet and tilt range is never an awful thing.


Thirdly, zooming capability of the cordless IP camera is also vital.

Ensure that you check the type of zooming capacity, whether its optical or digital.


Most of the IP cameras in the market are digital, but you'll never fail to find one with optical move.


Fourth, test the gear before purchase.

This is vital, particularly when you are buying from your local electronic store.


Always request for a test setup as this will permit you to look for the picture quality of the camera.


Furthermore, it will offer you an opportunity to learn how to create the gear in an effective manner to make certain you get the best image and music quality.
